StartSSL gives you some files that are encrypted. Before you install them you have to decrypt them. It is likely that you are trying to upload your encrypted key. You usually have to decrypt the key before installing it. StartSSL has a FAQ about it here. They say you need to use the command:

openssl rsa -in ssl.key -out ssl.key
